NAME

       oggThumb - creates thumbnails from an ogg video file

SYNOPSIS

       oggThumb [options] file1.ogv [ file2.ogv [ file3.ogv [...] ] ]

DESCRIPTION

       oggThumb creates Thumbnails from one or more ogg video files, at a given time position or a given frame number. It is also possible to cre-
       ate a series of thumbnails at different time or frame positions. The pictures can be created in JPG or PNG format and can be resized to any
       given size.

       The default naming of each thumbnail series follows the following rule:

       <filename_without_extension>_x.<picture_extension>

       Where  x starts with 0 and is incremented with every created thumbnail. So the thumbnails are successivly numbered by the appearence order.
       This is even valid, if time positions and frame numbers are mixed.

OPTIONS

       -t     Time at which a thumbnail should be created. More than one thumbnail time can be concatenated by commas. The times  can  be  set	by
	      integer or floating point values in seconds. If the time is not exactly matching, the next frame is used. The times don't have to be
	      sorted incrementally.

	      Example: -t 12.4,14.157,13.23

       -f     Number of a frame that should be created as a thumbnail. More than one thumbnail frame can be concatenated by commas. The frame num-
	      bers must be an integers. The frame numbers don't have to be sorted incrementally.

	      Example: -f 12000,13000,11000

       -s     Picture  output  size.  The  thumbnail is created in the size given as <width>x<height>.	If you want to include the thumbnails into
	      your webpage and you need to have a fixed width but dynamic height, you can set the dynamic axis to 0. So the aspect  ratio  of  the
	      video frame is kept. This is the same for setting width or height to 0.

	      Example: -s 0x100

       -o     Output format. This can be png or jpg. The default is jpg.

	      Example: -o png

       -n     Alternative thumbnail picture name. The % can be used within the name to indicate the counter placeholder.

	      In  case of more than one video file, the counter continuous throughout the different videos, so that the pictures are not overwrit-
	      ten.

	      If the name has an extension. This extension is used to identify the output picture format.

	      Example: -n myNo_%_thumb

EXAMPLE

       oggThumb -t 10.3,22.4,31.9,43.4,59.4 -f 1200 -s 0x100 myFile.ogv

       oggThumb -f 200,400,300,100 -t 3.54 -n %_thumb.png myfile.ogv mysecondfile.ogv

NAME

       oggCut - extracts parts of an ogg file (.ogv, .ogg and .oga)

SYNOPSIS

       oggCut [options] inputfile outputfile

DESCRIPTION

       oggCut creates a new ogg file named outputfile as a subpart of the original file named inputfile

       oggCut is able to cut video (theora) only files, audio (vorbis) only files or files with both video and audio streams.

       The start and end time for the cut area must be given in milliseconds with the options -s and -e.

       As  a video stream consists of I-frames (which are full pictures) and P-frames (which are delta pictures to the leading I-frame) the oggCut
       algorithm searches for the first I-frame. If a video file would start with a p-frame, the player is not able to interpret this picture,	as
       the leading I-frame (on where it is based) is not available.  oggCut starts the I-frame search at the start time given by the -s option. So
       expect a shorter video time than the calculated seconds for the new file.

       oggCut does not do any reencoding, therefore the output quality is completely the same as from the input file.

       For those involved into the ogg container format: The file is cut on packet basis, not on page basis.

       There is another tool called oggCut out in the internet with a different synopis. This one has not been written by the author of this  tool
       you are actually using.

OPTIONS

       -s     Cut start position in ms. If the input file is a video file, the cut area starts with the next keyframe found. Default: 0

	      Example: -s 5000

       -l     Length of the cut area in ms. If -e is also given, the length is ignored.

	      Example: -l 10000

       -e     Cut end position in ms. If -l is also used, the end position is prefered. If the end position is set to -1, the end of the stream is
	      assumed.

	      Default: -1

	      Example: -e 20000

EXAMPLE

       oggCut -s 1000 -e 21000 myVideo.ogv myOutput.ogv

       Creates a new video called myOutput.ogv from the video myVideo.ogv starting after 1 second ending after 21 seconds
